Whatever. Putting it on a tripod is the simplest way to eliminate hand shake. In fact that's why tripods were invented. But yes, we wouldn't want to eliminate hand shake as the source of the problem because that would might create cognitive dissonance in the minds of the shutter shock faithful.

Here it is again, plain evidence of increased blurriness in the shutter shock danger zone with hand shake eliminated:

Attaching the camera to something solid is likely to increase the risk of SS, hence the delay settings that you can set, this is even talked about in the camera manual.

And this is perfectly normal and to be expected under certain conditions.

At least by testing using a tripod you are eliminating most other causes of blur, such as hand shake etc.

Hand held the risk of SS diminishes.

The evidence texinwien points to indicates that blur due to SS can occur even when shooting from a tripod. It does not demonstrate that the risk of blur due to SS increases when shooting from a tripod.

In my own quite extensive testing with my E-M5, it is clearly the other way around. The risk/magnitude of blur due to SS declines when shooting from a tripod. Furthermore, when using a sufficiently heavy and sturdy "tripod" (such as the floor of my kitchen with tiles on top of conrete), there is no blur at all due to SS even with my 100-300 at 300 mm and no anti-shock delay.

The reason why a tripod can decrease the risk of blur due to SS is that one important mechanism (and the only one I have so far found clear-cut evidence for in the tests I have conducted with my own gear although I remain open to other possibilities) is that shutter action causes a displacement of the camera as a whole. The risk/magnitude of such displacement declines if the camera is put on a reasonably sturdy tripod and is eliminated altogether if it is put on a sufficently heavy and sturdy "tripod" of the type described above. In other words, given that SS causes blur via displacement of the camera as a whole, the risk/magnitude of such blur declines if the camera "has no place to go".
